Conditions at Belmar in May
May: Small but Sprightly
May begins to feel like summer, and the ocean responds accordingly. Average swell height falls to 3ft (1.0m) and the period settles back to 7.2s. The good news is direction: the favorable ENE/E/ESE/SE quadrant jumps to 51% of the swell spectrum, with SSE (19%), S (18%), and SE (16%) dominant. The bad news is size - most of that energy is in the 2-3ft (0.5-1m) and 3-5ft (1-1.5m) bands, so expect small, fun-sized, groveling waves rather than grinding barrels. On the positive side, offshore wind is favorable 37% of the time, and the lighter westerlies allow for cleaner sessions. Water temps become more manageable at 12.7°C, and air temps average 13.8°C. It is a good month for longboarders and grovelers.
